What kind of organism is a brain eating bug? What happens if you get infected?

The worm is called amoebic protozoa. It is a trophozoite oblong oval, with an average size of 22*7 microns, and an unrestrained pseudopod protrudes from one end, and moves rapidly. The cytoplasm is granular and contains several vesicles and telescopic vesicles.

A large nucleus can be seen on staining, the nucleolus is large, and there is a transparent circle between the nucleolus and the nuclear membrane. After 36 hours in distilled water, the trophozoites can transform into a pear-shaped, flagellar type with 2 or 4 flagella. <>

The flagellar form is transient and changes to the amoebic form after 24 hours. The cyst is round, about 9 microns in diameter, and the wall of the cyst is smooth with or without holes. Nuclei are homotrophozoites.

No cysts were seen in the tissue. It has two morphologies of amoeba and sporangia, and survives in vitro in the form of sporangia, which are approximately spherical, with a size of 6 7 lnill and strong refraction. The sporangia shell has a double membrane, the surface is smooth, difficult to color, the sporangia is filled with cytoplasm, there is a large nucleus in the middle, the nucleus contains a large nucleolus, and the sporangia will be excreted with the feces and become the source of infection.

Another form of amoeba is a variable unicellular body called amoeba, which is made up of a nucleus and cytoplasm. The damage is characterized by acute and widespread hemorrhagic necrotizing meningoencephalitis with a large number of trophozoites in cerebrospinal fluid and lesion tissue. Host susceptibility may be due to the absence of IgA, which weakens mucosal defenses.

Acanthamoeba is more widely distributed and is often found in respiratory secretions. <>

The primary site of the lesion is ** or the eyes, lungs, stomach, intestines, and ears, etc., causing inflammation and granulomas, and in the case of host immunosuppression or weakening, it may be transmitted to the central nervous system through hematogens and cause granulomatous amoebic encephalitis. Neurological signs show focal unilateral lesions with severe focal necrosis and edema. The patient suffers from headache, fever, vomiting, neck stiffness, dizziness, drowsiness, confusion, ataxia, and even coma and death.

However, those that have not metastasized to the brain are generally not fatal, and a few can heal spontaneously.

An organism that obtains the nutrients needed to survive, develop and reproduce in the host or host or outside the body can be malnourished and unhealthy when infected, resulting in death.

Brain-eating worms are parasites that multiply and survive in the brain, and after being infected, they will have various uncomfortable symptoms, such as headache, nausea and vomiting, and in severe cases, even affect our hearing.

Neegler fowleri is the scientific name of brain-eating amoeba and is an amoeba protozoa, which is divided into two categories: parasitic and free-living. Amoebic protozoa parasitic in humans can cause amoebic dysentery, and sometimes liver abscesses, lung abscesses, and meningitis. Free-living amoebic protozoa include Acanthamoeba spp., Natanshoutri spp., Haeba's spp., and E. valdorii, many of which can cause disease in humans.

The "brain-eating worm", officially known as Naegleria fowleri, is a highly pathogenic single-celled protozoa, mostly 10-30 microns, that can infect humans in lakes or rivers, causing primary amoebic meningitis. Amoeba Negri infection causes swelling of the brain, causes increased intracranial pressure, and puts tremendous pressure on the skull, forcing the connection between the brain and the spinal cord to be separated, and the mortality rate is more than 97%, so it is vividly called "brain-eating worm".

Trophozoites, flagellates and vesicles of brain-eating worms.

1. How harmful is the "brain-eating worm" infection to the body?

Brain-eating insects can generally only enter the human body through the nasal mucosa, and after entering the nasal cavity, along the olfactory nerve, they are attracted by the "acetylcholine" released by the cells at the front of the brain, and will reach the subarachnoid hollow space of the brain (there is a large amount of cerebrospinal fluid, and the temperature is also very suitable for its reproduction), and the brain is used as a "destination" for camping, where a large number of reproduction brain-eating insects will gradually invade the entire central nervous system of the human body.

2. The initial symptoms of infection

None of the creatures on earth are simple. The "brain-eating worm" is a single-celled organism with a short incubation period, usually about 5 days to show symptoms. In the early stage of the disease, the symptoms of nasopharyngitis are accompanied by changes in taste and smell, followed by headache, fever, nausea, vomiting, etc., and the disease progresses rapidly, which can cause patients to have symptoms such as neck stiffness, impaired consciousness, lost consciousness, loss of balance, hallucinations, and breathing disorders.

3. How to prevent infection?

A person cannot become infected with the "brain-eating worm" by drinking contaminated water, but a person can become infected with the parasite when their nose comes into contact with contaminated water. The months in which the cryptoparasite is said to be infected usually occur in the month of January, when the water level is low and the water temperature is high. To prevent infection with this parasite, the following precautions can be done:

Avoid contact with water in the wild through your nose. The agency also advises people to avoid water-related activities in warm fresh water or near power plants.

If you develop symptoms after swimming in warm water, you should seek medical attention immediately.

When water-related activities must be engaged, it is best for people to use nose clips, as well as boiled or sterile water for nasal lavage.

If you have suspicious symptoms such as headache, vomiting, abnormal sense of smell, or fever after swimming, do not delay for a moment and seek medical attention immediately.

The so-called "brain-eating worm" actually refers to a parasite called Naegleria fowleri, which mainly exists in natural water bodies, such as mud, ponds, rivers, etc. Infection with Trypanosoma nixiosenosa causes severe brain infections and inflammation, resulting in a very high mortality rate. Specific hazards include:

Meningitis: After Trypanosoma nixinose enters the body through the nose, it can invade the brain and meninges, causing symptoms such as meningitis and intracranial hypertension.

Encephalitis: An infectious disease caused by viruses invading brain tissue, which can cause fever, headache, impaired consciousness, convulsions, and even life-threatening.

Nervous system damage: Trypanosoma nixtoenosis can multiply in the brain and nerve tissue, causing severe damage and destruction to the nervous system.

The initial symptoms of infection are mostly flu-like symptoms, such as fever, headache, cough, fatigue, etc., but as the disease worsens, severe brain symptoms may appear, such as nausea, vomiting, neck stiffness, impaired consciousness, coma, etc. If you suspect you have Trypanosoma nickeri infection, you should seek medical attention immediately.

It is not contagious, there are only more than 100 cases of patients with this disease in the United States in the past half century, and the infection rate is extremely low, so the possibility of infection is almost none, but this disease is indeed terrible, because its fatality rate is close to 100%, and only a few of the more than 100 people can survive, if this disease can be transmitted, then it is absolutely the end of mankind. <>

First, the terrible brain-eating worm is called "amoeba protozoa", mainly living in some warm areas of water, when the amoeba protozoa into the human brain will continue to eat the human brain, at first the human body will appear drowsy, body chain fatigue and other symptoms, the average person will only think that Wang Xin is a common cold, and then as the amoeba in the body for longer and longer, the human body will become worse and worse, and gradually appear nausea, fever, headache and other symptoms, In addition, epilepsy and hallucinations may occur, and it can be said that the person is hopeless when the latter symptoms occur. <>

Second, the mode of transmission of amoebas and the scope of life of amoebas is constantly expanding, there are already people who have died because of "primary amoebic meningitis" in China, but there is no need to panic, it has been said earlier that the infection rate of this disease is extremely low, the main reason is because there is only one way for amoebas to enter the human body, that is, through the nasal passage will enter the brain, usually even if you drink water containing amoebic will not be infected, so it seems that this disease is not terrible, As long as safety precautions are taken, the possibility of developing this disease can be eliminated. <>

Third, do a good job of preventive measures, do a good job of safety precautions The first step is to try to avoid swimming in the wild water source, even if the canopy orange is in the water, the nasal cavity and other facial organs should also try not to contact wild water sources, and secondly, do not drink wild water sources, and finally after swimming in the wild, people who find that there is an abnormality in the body do not delay must go to the hospital to check the body, although the fatality rate of this disease is extremely high, but there is still a survival rate.
